Rocha strutted down the runway in simple snow-colored ankle booties, while her little one sported sweet Mary Janes in the same pristine shade.

The 29-year-old model — who is pregnant with her second child, a son — and Ioni also showed off identical hairstyles that looked straight out of Whoville from “The Grinch Stole Christmas.”

Rocha took to social media to document the special experience, sharing several posts to Instagram today. The expectant mom captioned one shot of Ioni getting fitted for her dress before the show: “Only two years old and already a pro at couture fittings in Paris.”

In a video of the mother-daughter duo doing their thing on the catwalk, Rocha wrote, “Carrying my son in my belly with my daughter @ioniconran by my side, I will never forget this day! Thank you @jpgaultierofficial for another unforgettable moment on the runway, my heart is so full.”
